Answer:

2.14*10^{-3} mol

Explanation:

number of moles of C8H9NO2 = \frac{mass}{molar mass}=\frac{324*10^{-3} g}{151.163g/mol}=2.14*10^{-3}mol

The trick is to remember to convert milligrams to grams because molar mass is normally presented in grams per mole

If a chemist has a stock solution of HBr that is 10.0 M and would like to make 450.0 mL of 3.0 M HBr, how would he do it?
asambeis [7]

This is a dilution that requires a certain volume from the stock solution to be diluted with distilled water to make a solution of HBr with a lesser concentration than the stock solution

Following dilution formula can be used

c1v1 = c2v2

Where c1 is concentration and v1 is the volume of the stock solution

c2 is concentration and v2 is volume of the diluted solution to be prepared

Substituting these values

10.0 M x v1 = 3.0 x 450.0 mL

v1 = 135.0 mL

A volume of 135.0 mL from HBr stock solution needs to be taken and diluted with distilled water upto 450.0 mL. The resulting solution will have a concentration of 3.0 M

What’s the answer to this science problem?
Law Incorporation [45]

Answer:

The image is not accurate because

the heavier atoms are moving faster than the lighter ones

but the lighter ones must move faster than the heavier ones.

Explanation:

The image depicts the atoms of two different elements; atoms of lighter and heavier elements.

And the rate of diffusion (movement of atoms) of an element is inversely proportional to the square root of its molecular.

⇒ As the weight increases, the rate of diffusion (movement of atoms) decreases.

And as the weight decreases, the rate of diffusion (movement of atoms) increases.

so, heavier atoms move slowly compared to lighter atoms.

The image is not accurate because

the heavier atoms are moving faster than the lighter ones

but the lighter ones must move faster than the heavier ones.

Which of the following is one way to prevent the corrosion of iron? 
Drupady [299]
B: Painting over a metal surface in order to prevent rust is known as rust proofing and it works by preventing oxygen and water from reaching the metal surface thus preventing a redox reaction which would result in rusting.
